Although the standard Spider Solitaire game still is a highly popular game, the 2-Suit Spider Solitaire variant has rapidly gained in popularity due to retaining what makes the classic Spider game so good, while making it much more accessible to the average player. For example, on Solitaire Network, standard Spider is only won about 4% of the time and is a very difficult game that requires more than the usual amount of strategy and concentration, whereas the the Spider Solitaire 2-suits variation is won about 18% of the time and is a more relaxed version. It is a great introduction to the game of Spider for most people.
The goal in 2-suit Spider Solitaire is the same as in most other Spider games: Arrange eight sets of cards from King down to Ace in the same suit directly within the Columns.
2-Suit Spider uses two decks (four sets of Ace through King in Hearts, and another 4 sets in Spades. There are ten Columns and each Column is dealt either 5 or 6 cards. The first four Columns are dealt 6 cards, and the remaining six Columns are each dealt 5 cards. Only the top card in each Column is dealt face up.
Every click on the Stock will deal one card to each Column. Click on the Stock after no more moves are possible (or desirable) in the layout. All Columns must contain at least one card before the cards will be dealt. There are no redeals.
Columns are built DOWN in ANY SUIT. However, you should prefer building cards that are of the same suit, since that is the goal. But it may become necessary or advantageous to build the opposite suits at times.
The fully exposed card of each Column is always available to move. Also, cards of the same suit and in proper sequence can be moved to another Column provided the above build rule applies. As an example, a 5, 4, and 3 of Hearts may move to any 6. However, an 5 of spades, and then a 4 and 3 of Hearts may not move as a unit because they are not all of the same suit.
Sequences may be split apart once formed. For example, in a sequence such as the 5, 4, and 3 of Hearts, the 4 and 3 may be moved away from from the 5 of Hearts so that it can be played to any other 5.
When a full sequence of King through Ace in the same suit is arranged within a Column, it is removed from the layout (tableau.)
Empty Columns can be filled with any single card or packed sequence of cards. All Columns must contain at least one card before more cards can be dealt from the Stock.
One point is scored for each built card within Columns starting with a King. For example, if a Column has a King, Queen, and Jack of the same suit in sequence then that will score three points. Hence, a fully packed set of King through Ace in the same suit scores 13 points.
2-Suit Spider Solitaire plays identically to standard Spider Solitaire except that only two suits are used: Hearts and Spades. Spider Solitaire 2-Suits is Solitaire Network's most popular variant of Spider by a significant margin.
